In this paper, the authors consider the routing problems for wireless sensor networks. Wireless sensor networks consist of number of sensor nodes, sink or gateway sensor node. The important issue in the wireless sensor networks is collecting information from sensor nodes and sending data to the sink node or data concentration centre (gateway) at the correct time. And the data are monitored through the sink node. The development of sensor networks was motivated by military applications and civil applications. Here, they discuss and compare about various routing protocols for wireless sensor networks.
